Dr. Marie Billaud is a Research Assistant Professor in the Department of Cardiothoracic Surgery, University of Pittsburgh School of Medicine, and in the Thoracic Aortic Disease Research Lab of the McGowan Institute. Dr. Billaud received her PhD from the Université de Bordeaux in France where her doctoral research was focused on intercellular communication, reactive oxygen species and nitric oxide signaling, and how they regulate vascular tone in the pulmonary circulation. Dr. Billaud further worked as a post-doctoral fellow and an Instructor of Research at the University of Virginia, where her project was to identify the role of a newly discovered protein (pannexins) in the adrenergic-mediated regulation of vascular tone and blood pressure.
Dr. Billaud joined the University of Pittsburgh in January 2014, where her primary goal is to investigate potential impairment of TGF-β signaling and biomechanical sensing in smooth muscle cells from patients with thoracic aortic aneurysm. In parallel, she integrates her knowledge in reactive oxygen species signalization to identify the mechanisms behind the impaired oxidative stress response in patients with bicuspid aortic valve that was identified by the Gleason Lab. Lastly, Dr. Billaud incorporates her skills in vasoreactivity to investigate the contractile function of aortic vasa vasorum from patients with thoracic aortic aneurysm.
Dr. Billaud’s work has been published as original research articles and cover art in journals such as Circulation Research, Arteriosclerosis, Thrombosis and Vascular Biology, Stem Cell Reports, and Journal of Thoracic and Cardiovascular Research. She also serves as a peer reviewer for Microcirculation, Journal of Biological Chemistry, Journal of Cardiovascular Translational Research, Stem Cells, American Journal of Physiology, Science Advances and PlosOne.
